Use GetTagKeys with a CLI

To get a list of all tag keys

The following get-tag-keys example retrieves the list of all tag key names used by resources in the account.

aws resourcegroupstaggingapi get-tag-keys

Output:

{
    "TagKeys": [
        "Environment",
        "CostCenter",
        "Department"
    ]
}

For more information, see GetTagKeys in the Resource Groups Tagging API Reference.

Example 1: Returns all tag keys in the specified region. If the -Region parameter is not specified the cmdlet will attempt to infer the region from the default shell region or EC2 instance metadata. Note that the tag keys are not returned in any specific order.

Get-RGTTagKey -region us-west-2
